-/**\r
-* @class Ext.XTemplate\r
-* @extends Ext.Template\r
-* <p>A template class that supports advanced functionality like autofilling arrays, conditional processing with\r
-* basic comparison operators, sub-templates, basic math function support, special built-in template variables,\r
-* inline code execution and more. XTemplate also provides the templating mechanism built into {@link Ext.DataView}.</p>\r
-* <p>XTemplate supports many special tags and built-in operators that aren't defined as part of the API, but are\r
-* supported in the templates that can be created. The following examples demonstrate all of the supported features.\r
-* This is the data object used for reference in each code example:</p>\r
-* <pre><code>\r
-var data = {\r
- name: 'Jack Slocum',\r
- title: 'Lead Developer',\r
- company: 'Ext JS, LLC',\r
- email: 'jack@extjs.com',\r
- address: '4 Red Bulls Drive',\r
- city: 'Cleveland',\r
- state: 'Ohio',\r
- zip: '44102',\r
- drinks: ['Red Bull', 'Coffee', 'Water'],\r
- kids: [{\r
- name: 'Sara Grace',\r
- age:3\r
- },{\r
- name: 'Zachary',\r
- age:2\r
- },{\r
- name: 'John James',\r
- age:0\r
- }]\r
-};\r
-</code></pre>\r
-* <p><b>Auto filling of arrays and scope switching</b><br/>Using the <tt>tpl</tt> tag and the <tt>for</tt> operator,\r
-* you can switch to the scope of the object specified by <tt>for</tt> and access its members to populate the template.\r
-* If the variable in <tt>for</tt> is an array, it will auto-fill, repeating the template block inside the <tt>tpl</tt>\r
-* tag for each item in the array:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>Name: {name}</p>',\r
- '<p>Title: {title}</p>',\r
- '<p>Company: {company}</p>',\r
- '<p>Kids: ',\r
- '<tpl for="kids">',\r
- '<p>{name}</p>',\r
- '</tpl></p>'\r
-);\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r
-* <p><b>Access to parent object from within sub-template scope</b><br/>When processing a sub-template, for example while\r
-* looping through a child array, you can access the parent object's members via the <tt>parent</tt> object:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>Name: {name}</p>',\r
- '<p>Kids: ',\r
- '<tpl for="kids">',\r
- '<tpl if="age &gt; 1">', // <-- Note that the > is encoded\r
- '<p>{name}</p>',\r
- '<p>Dad: {parent.name}</p>',\r
- '</tpl>',\r
- '</tpl></p>'\r
-);\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r
-* <p><b>Array item index and basic math support</b> <br/>While processing an array, the special variable <tt>{#}</tt>\r
-* will provide the current array index + 1 (starts at 1, not 0). Templates also support the basic math operators\r
-* + - * and / that can be applied directly on numeric data values:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>Name: {name}</p>',\r
- '<p>Kids: ',\r
- '<tpl for="kids">',\r
- '<tpl if="age &gt; 1">', // <-- Note that the > is encoded\r
- '<p>{#}: {name}</p>', // <-- Auto-number each item\r
- '<p>In 5 Years: {age+5}</p>', // <-- Basic math\r
- '<p>Dad: {parent.name}</p>',\r
- '</tpl>',\r
- '</tpl></p>'\r
-);\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r
-* <p><b>Auto-rendering of flat arrays</b> <br/>Flat arrays that contain values (and not objects) can be auto-rendered\r
-* using the special <tt>{.}</tt> variable inside a loop. This variable will represent the value of\r
-* the array at the current index:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>{name}\'s favorite beverages:</p>',\r
- '<tpl for="drinks">',\r
- '<div> - {.}</div>',\r
- '</tpl>'\r
-);\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r
-* <p><b>Basic conditional logic</b> <br/>Using the <tt>tpl</tt> tag and the <tt>if</tt>\r
-* operator you can provide conditional checks for deciding whether or not to render specific parts of the template.\r
-* Note that there is no <tt>else</tt> operator — if needed, you should use two opposite <tt>if</tt> statements.\r
-* Properly-encoded attributes are required as seen in the following example:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>Name: {name}</p>',\r
- '<p>Kids: ',\r
- '<tpl for="kids">',\r
- '<tpl if="age &gt; 1">', // <-- Note that the > is encoded\r
- '<p>{name}</p>',\r
- '</tpl>',\r
- '</tpl></p>'\r
-);\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r
-* <p><b>Ability to execute arbitrary inline code</b> <br/>In an XTemplate, anything between {[ ... ]} is considered\r
-* code to be executed in the scope of the template. There are some special variables available in that code:\r
-* <ul>\r
-* <li><b><tt>values</tt></b>: The values in the current scope. If you are using scope changing sub-templates, you\r
-* can change what <tt>values</tt> is.</li>\r
-* <li><b><tt>parent</tt></b>: The scope (values) of the ancestor template.</li>\r
-* <li><b><tt>xindex</tt></b>: If you are in a looping template, the index of the loop you are in (1-based).</li>\r
-* <li><b><tt>xcount</tt></b>: If you are in a looping template, the total length of the array you are looping.</li>\r
-* <li><b><tt>fm</tt></b>: An alias for <tt>Ext.util.Format</tt>.</li>\r
-* </ul>\r
-* This example demonstrates basic row striping using an inline code block and the <tt>xindex</tt> variable:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>Name: {name}</p>',\r
- '<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',\r
- '<p>Kids: ',\r
- '<tpl for="kids">',\r
- '<div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',\r
- '{name}',\r
- '</div>',\r
- '</tpl></p>'\r
-);\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r
-* <p><b>Template member functions</b> <br/>One or more member functions can be defined directly on the config\r
-* object passed into the XTemplate constructor for more complex processing:</p>\r
-* <pre><code>\r
-var tpl = new Ext.XTemplate(\r
- '<p>Name: {name}</p>',\r
- '<p>Kids: ',\r
- '<tpl for="kids">',\r
- '<tpl if="this.isGirl(name)">',\r
- '<p>Girl: {name} - {age}</p>',\r
- '</tpl>',\r
- '<tpl if="this.isGirl(name) == false">',\r
- '<p>Boy: {name} - {age}</p>',\r
- '</tpl>',\r
- '<tpl if="this.isBaby(age)">',\r
- '<p>{name} is a baby!</p>',\r
- '</tpl>',\r
- '</tpl></p>', {\r
- isGirl: function(name){\r
- return name == 'Sara Grace';\r
- },\r
- isBaby: function(age){\r
- return age < 1;\r
- }\r
-});\r
-tpl.overwrite(panel.body, data);\r
-</code></pre>\r

-* @param {String/Array/Object} parts The HTML fragment or an array of fragments to join(""), or multiple arguments\r
-* to join("") that can also include a config object\r
